PHENYLPHOSPHINE OXIDE AND OXYGEN STABLE EPOXY POLYMERS AND METHODS OF SYNTHESIS

A polymer formed of at least one phenylphosphine oxide functional epoxide crosslinked with at least one phenylphosphine oxide amine such that the polymer has phosphorous concentrations of at least about 8 percent by weight, at least about 8.5 percent by weight, or any value or range of values therebetween.

Flame retardant polycyanurate thermosets from the cyanate esters of triphenylphosphine oxide

Three cyanate esters containing phosphorus are synthesized in good overall yields starting from bromoanisoles. Di- and tricyanates with meta configuration are most stable while para is less so. The para dicyanate ester isomer is particularly affected by water from the atmosphere. The meta dicyanate ester 2 has good thermal properties with glass transition at 268 °C and char yield of 65% in air at 600 °C. All three phosphorus-containing cyanate esters are low flammability in an open flame. They make highly combustible cyanate esters resins less flammable simply by blending. Mixing 10 wt% dicyanate ester 2 into bisphenol A or E dicyanate esters makes them rate V-0. Published 2018.? J. Polym. Sci., Part A: Polym. Chem. 2018, 56, 1100–1110.
